Abstract
Described herein are systems and methods for determination of rolling resistance from a sensor or sensors in a tire or tires for application in smart cars to provide feedback to interested parties, such as Departments of Transportation or tire manufacturers.
Claims15
A system for monitoring rolling resistance across a road comprising:
- a vehicle with at least one tire;
- the at least one tire having at least one soft elastomeric capacitor tire sensor incorporated into a structure of the tire;
- and
- wherein movement of the at least one tire across a road surface impacts the at least one soft elastomeric capacitor tire sensor and provides rolling resistance data for the at least one tire.

A method for calculating rolling resistance across a road comprising:
- forming at least one tire having at least one soft elastomeric capacitor tire sensor incorporated into a structure of the tire;
- placing the tire on a vehicle;
- placing at least one force sensor within a suspension of the vehicle in communication with the at least one soft elastomeric capacitor tire sensor;
- and
- wherein movement of the at least one tire across a road surface impacts that at least one soft elastomeric capacitor tire sensor and provides rolling resistance data for the at least one tire.
